45 Degree Elbow, Slip x Slip PVC Schedule 40 2-1/2" (417-025)

This 2-1/2" Schedule 40 PVC 45 Degree Elbow provides a permanent, solvent-cemented 45° directional change in a Schedule 40 PVC pressure piping system, routing a 2-1/2" pipe run through a half-right-angle turn in a single fitting. Both slip socket ends accept standard 2-1/2" PVC pipe for solvent cement joining, producing a fully solvent-welded 45° directional change that becomes a continuous, integral part of the piping system once cured.

Two parallel distinctions define where the 417-025 belongs in a system layout. The first is connection type. Within the Schedule 40 45° elbow family at 2-1/2", the 417 all-socket series serves fully solvent-welded PVC pipe systems where both sides of the 45° turn are cemented pipe ends — the correct configuration wherever the run on both sides of the directional change is plain PVC pipe joined by solvent cement. A mixed-configuration 45° elbow with a female-threaded outlet (418-series) bridges a solvent-welded inlet to a threaded component at the turn. When both connections at the directional change are solvent-welded pipe, the 417-025 is the correct selection.

The second distinction is turn angle. The 417-025 produces a 45° turn — a half-right-angle directional change that serves a fundamentally different set of layout requirements than the 90° turn of the 406-series Slip × Slip elbow. Where a 90° elbow makes an abrupt right-angle turn at the direction change point, the 45° elbow routes the pipe run through a shallower angular offset — enabling diagonal routing around structural members, equipment footprints, and spatial constraints; gradual directional transitions in congested piping layouts; compound-angle assemblies where two 45° elbows work together to create a custom lateral offset or a 90° turn with displacement between inlet and outlet centerlines; and direction changes where reducing flow turbulence and pressure drop at the turn is a design consideration. The 45° geometry is the correct selection wherever the piping layout requires an angular transition that a single 90° elbow cannot accomplish cleanly, or wherever the shallower sweep is specified for hydraulic efficiency at the directional change.

At 2-1/2", the 417-025 serves an intermediate pipe size that appears at specific flow requirements where 2" falls short of the required flow capacity and 3" exceeds it. This intermediate sizing role means the 2-1/2" pipe size appears at targeted applications — specific pump discharge runs, equipment supply connections, and distribution headers with defined flow requirements that land precisely in the 2-1/2" hydraulic range. In these systems, the 45° elbow at this size provides the same diagonal routing, compound-angle, and flow-efficiency advantages as at other pipe sizes, but at a pipe size where the elbow's availability and correct specification are worth confirming given the less common stocking status of 2-1/2" fittings relative to the adjacent 2" and 3" sizes.

Manufactured in white Schedule 40 PVC, this elbow delivers reliable performance across residential, commercial, and light industrial piping applications at this intermediate pipe size. PVC's resistance to acids, bases, salts, chlorine, and common process fluids provides long service life in environments where metal elbows would corrode or scale. NSF/ANSI 61 and NSF/ANSI 14 listings confirm suitability for potable water contact.

Rated to 300 psi at 73°F, this fitting handles standard pressure service across irrigation, water distribution, and process piping applications at the 2-1/2" pipe size. For installation, clean and dry both pipe ends and socket interiors before application. Apply purple PVC primer to all mating surfaces — both pipe ends and both socket interiors. At 2-1/2", use a medium-body PVC solvent cement; apply a uniform coat to both the pipe end and socket interior at each end before joining. Insert the pipe with a slight quarter-turn twist and hold firmly for 30 seconds to prevent pushback. Plan and confirm the 45° turn orientation before cementing — the direction of the angular offset is set permanently at installation and cannot be adjusted after the joints are cured. Stagger the two joints where possible and allow full cure time per the cement manufacturer's temperature and humidity guidelines before pressurizing. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Commercial Plumbing & Water Distribution — Routes 2-1/2" Schedule 40 PVC solvent-welded water supply mains and distribution headers through 45° directional changes at diagonal routing transitions, structural clearance offsets, and angular direction changes in commercial building plumbing systems where the 2-1/2" pipe size serves the specific flow requirement between smaller 2" and larger 3" distribution mains and a 90° turn would create layout geometry or clearance conflicts at the direction change point
• Industrial Process Piping — Provides a 45° solvent-cemented directional change on 2-1/2" Schedule 40 PVC process lines, equipment supply headers, and distribution runs at structural clearances, equipment footprint offsets, and diagonal routing transitions in chemical processing, water treatment, and light manufacturing facility piping where the 2-1/2" intermediate pipe size is specified and the 45° elbow serves the angular routing requirement
• Irrigation & Agriculture — Routes 2-1/2" Schedule 40 PVC solvent-welded submain and mainline headers through 45° turns at field boundary offsets, pump station outlet routing transitions, buried mainline diagonal alignments, and above-grade routing changes in large-scale commercial and agricultural irrigation systems where the 2-1/2" pipe size serves zone or sector flow requirements between smaller laterals and larger mains
• Compound-Angle Routing — Used in pairs to create a custom lateral offset or a 90° turn with centerline displacement in 2-1/2" Schedule 40 solvent-welded systems — a two-elbow compound configuration that achieves routing transitions not possible with a single 90° elbow in congested equipment rooms, pump station layouts, and distribution assemblies at the 2-1/2" intermediate pipe size
• Water & Wastewater Treatment — Redirects 2-1/2" Schedule 40 PVC process piping at 45° routing transitions on filter vessel connections, pump discharge runs, chemical distribution headers, and secondary distribution piping in municipal and industrial water treatment facilities where the 2-1/2" pipe size meets specific hydraulic design requirements and the 45° geometry suits the spatial routing constraints at the direction change point
• Pool, Spa & Aquaculture — Routes 2-1/2" PVC recirculation, filtration, and backwash piping through 45° turns at equipment pad routing transitions, pump inlet approach angles, filter vessel connections, and underground pipe run offsets in aquatic facility and water feature installations where the intermediate 2-1/2" pipe size serves the system flow requirements and the 45° geometry provides the correct angular offset for the equipment layout
• Site Utilities & Pump Station Piping — Provides 45° directional changes on 2-1/2" Schedule 40 PVC buried and above-grade utility water mains, pump station discharge headers, and site distribution piping at diagonal routing alignments, grade transitions, and equipment clearance offsets where the 2-1/2" intermediate pipe size and 45° elbow geometry are both specified in the hydraulic and layout design
